Well, theoretically at least, the build-system could be located outside 
the boost hierarchy and know nothing about it. So I usually have my 
jamfiles check for the BOOST_ROOT variable first and then, if that 
fails, I try find boost from BOOST_BUILD_PATH assuming a default boost 
installation.

I believe, the attached file, which I am currently using in my local 
Phoenix-V2 copy, has all the logic you need. Once you have the 
boost-root variable determined, you may use it as (incorporating other's 
suggestions)

     project yours :
         requirements <include>$(boost-root) ;

or

     project yours :
         requirements <use>$(boost-root)//headers ;

or still

     run myfile $(boost)//headers ;

HTH,
